Ex 9.1, 1

Ex 9.1, 1
Which of the following figures lie on the same base and between the same parallels. In such a case, write the common base and the two parallels.
(i)
Since
ABCD & PDC have same base DC
AB ∥ DC
P lies on AB and
Hence ABCD & PDC lie on same base DC and between same parallel lines AB & DC
Ex 9.1, 1
Which of the following figures lie on the same base and between the same parallels. In such a case, write the common base and the two parallels.
(ii)
Since MN does not lie on PQ
The two figures don’t lie on same base and between same parallels
Ex 9.1, 1
Which of the following figures lie on the same base and between the same parallels. In such a case, write the common base and the two parallels.
(iii)
Since
PQRS & TQR have same base QR
PS ∥ QR
T lies on PS and
Hence PQRS & TQR have same base QR and between same parallel lines PS & QR
Ex 9.1, 1
Which of the following figures lie on the same base and between the same parallels. In such a case, write the common base and the two parallels.
(iv)
Since ABCD & PQR don’t have a common base.
So, the two figures do not lie between the same parallel lines & common base
Ex 9.1, 1
Which of the following figures lie on the same base and between the same parallels. In such a case, write the common base and the two parallels.
(v)
Since
ABCD & PQDA have same base AD
AD ∥ BQ
PQ lies on BQ and
Hence ABCD & PQDA have same base AD and between same parallel lines AD & BQ
Ex 9.1, 1
Which of the following figures lie on the same base and between the same parallels. In such a case, write the common base and the two parallels.
(vi)
Here BCD & PQRS don’t have a common base.
So, the two figures do not lie between the same parallel lines & common base
